MetaMask About

MetaMask provides mobile and browser-extension access to a crypto wallet that users control themselves. Users can store assets, send tokens and manage NFTs. It also supports swaps, bridges and connections to DeFi platforms, games and other dApps.

Supported networks include Ethereum and its Layer 2 networks. In its standard self-custody setup, MetaMask does not store your Secret Recovery Phrase or private keys on its own servers. Instead, wallet credentials are kept locally on the user’s device and protected by the user’s password or device security.

For supported web apps, MetaMask can expose a wallet provider that lets sites request connections, signatures, and transactions with the user’s approval. These connections support DeFi and other onchain tools. MetaMask users remain exposed to phishing, fake extensions, risky approvals and device compromise. Other hot wallet options and self-custodial wallets differ in network coverage and recovery options.

MetaMask Mobile can pair with Ledger Nano X over Bluetooth, while the browser extension uses USB for Ledger connections. These Ledger accounts are limited to EVM networks.

MetaMask Features & Specs

  • Browser and mobile apps store wallet credentials locally in the standard seed phrase setup.
  • Supported blockchain apps can request connections, signatures and transactions, which require user approval.
  • Users control their recovery information and must check permissions before signing. A wallet connection does not make an application safe.
